Expired articles/Scrapped Article Issues

Hello good people,
I saw a few threads over here, where BHW sellers are offering hundreds of niche related expired articles at cheap price.
But I am afraid if I can use those ones for my money site or backlinks.
Could you please share your experience regarding this?
Is there any chance of getting slapped by Google anyway?
Does the big G keeps any cached version of those contents and compare those one while crawling?
What if I use those articles (CS passed) aggressively?
Sharing any practical experience would be appreciated.
Thanks a lot in advanced guys.
Happy marketing..

The sellers are providing these as Copyscape passed, so that should be fine.
I'd not suggest you use just these types of articles though on a site, make sure you have your own unique content on there too.

Some of these articles are fine for inner pages on a site, others are great for PBNs and Web2.0s.

Other option if your still concerned is pay more and buy brand new content, or write your own my friend.

You can double-check the expired articles manually through plagiarism checker tools if you wanted to be really sure. Make sure the content is not indexed anywhere. Though there are cases a DMCA takedown notice might occur. But I suggest you go for unique content for your moneysites.
